How to replace for-loops with a functional statement in C#?

Question

A colleague once said that God is killing a kitten every time I write a for-loop.

When asked how to avoid for-loops, his answer was to use a functional language. However

Answer 1

You can refactor your code well enough so that you won't see them often. A good function name is definitely more readable that a for loop.

Taking the example from AndyC :

Loop

// mystrings is a string array
List myList = new List();
foreach(string s in mystrings)
{
    if(s.Length > 5)
    {
        myList.add(s);
    }
}

Linq

// mystrings is a string array
List myList = mystrings.Where(t => t.Length > 5)
                               .ToList

Wheter you use the first or the second version inside your function, It's easier to read

var filteredList = myList.GetStringLongerThan(5);

Now that's an overly simple example, but you get my point.
